Why do humans see green? Probably because our monkey forebears, who lived in trees and ate leaves, needed to distinguish red leaves and red fruit (visible to birds) from the green background
We don’t evolve things cause we need it, evolution is driven by random mutations. Also we keep it if it’s better and helps us stay alive long enough to breed.
I mean, you’re really just arguing the semantics of phrasing.
Developing the ability to see green through random mutation was potentially an evolutionary advantage that allowed them to become better adapted to survival. Which is what they meant by “needed.”

I feel like OP covered that.
